With playlists, you can put a series of videos all in one handy place. For example, you could create a playlist of all of our favorite music videos or sports clips, then watch them together.
Once viewing a video in YouTube, click “Add to”
Add to an existing playlist or create a new playlist by entering the name in the box indicated.
Once added correctly you will receive the notification below. Add further information in the “Add an optional note” section.
On the left hand side of your screen click “Playlists”
In Playlists, click on the one you would like to share or play all, or click on the name of the Playlist to view Playlist Options
Share you link with viewers and they will be able to view your entire playlist.
